23 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
25 Enabled VPATH feature: changed nearly all Makefiles (149 files).
26 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
28 One basic decision: e.g. src/clean.mk includes further files. In order
29 to make this work there are two solutions:
30 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
31 run configure on them. This way they can use
32 'include $(srcdir)/port-clean.mk'
33 - always include clean.mk by the Makefile at the same level. To avoid
34 that `make clean` tries to include and build Makefile.dep the
35 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
36 implemented, because now even `make uninstall` doesn't create
37 Makefile.in. clean.mk could be eliminated by pasting it in
40 * debugger/mcs51/Makefile.in: build own objects from library sources
41 (SLIB, SDCC) in current directory
43 * configure, configure.in: renamed --disable-device-lib-build in
44 --disable-device-lib; added --enable-doc, the required tools are
45 searched by configure; added result message; the toolchain for the
46 belonging ports are now only built, if the port is enabled.
48 * support/regression/*: all output is written in directory gen, because
49 the fwk and ports directories don't livet in the build tree using vpath
51 * doc/sdccman.lyx: renamed --disable-device-lib-build to
52 --disable-device-lib, added --enable-doc, added section VPATH
54 * sim/ucsim/configure.in,
55 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
56 z80 are enabled by default
58 2006-04-24 Raphael Neider <rneider AT web.de>
60 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments to

63 config word has been found
64 * src/pic/device.h: added prototypes

371 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
372 call to allocReg, not by manually allocating a new one,
373 (pic16_assignRegisters): now before going through the register
374 allocating functions mark all registers as free. This eliminates some
375 side effects resulting from peephole parser done earlier in the backbone

442 (genFunction, genEndFunction): do not store/restore local registers for
443 _main (this should take care the --main-return command line option in
445 (genOr): removed some legacy pic-port instructions,
446 * src/pic16/genarith.c (genAddLit): re-enabled old code because
447 performing operations with SFR's causes data to be written more than
448 once to each SFR. Perhaps SFRs should be handled in special cases...
449 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
451 * src/pic16/main.c (_process_pragma): stack bound checking did not take
452 into account for stack starting position,

454 --extended or -y for Extended Instruction Support,

457 (commented out for reference), didn't account for some registers which
458 were left marked 'not free' after a pointer operation. The change
459 reduces register usage a lot in some cases

2734 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2735 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2736 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2737 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2738 always available in leading double underscore form. The C99 support is
2739 mostly missing, but it's a start.
2740 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2741 reserved identifier "__data".

2819 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2821 * device/lib/printf_large.c: removed inline assembly for portability and
2822 readability. Use printf_fast if speed or size are more important.
2823 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2824 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2826 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2828 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2829 prevent compiler warning
2831 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2833 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2834 moved to level 0 and declared as static. Also they are explicit
2835 placed in access bank. This was necessery because some times they
2836 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2837 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2838 optimizations. Currently only compare to unsigned char is implemented,
2839 * src/pic16/gen.c: added fReturnIdx array,
2840 * (struct resolvedIfx) is moved to gen.h and made public,
2841 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2842 * (aopForSym): added an optimization to directly store in stack of
2843 the operand of a SEND iCode,
2844 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2845 but as registers instead (AOP_REG) using the fReturnIdx array,
2846 * (pic16_freeAsmop): remove the freed register from the
2847 _G.sregsAlloc field,
2848 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2849 a compare of 'WREG',
2850 * (pic16_popGetTempRegCond): changed function prototype, now
2851 function takes also a bitVector argument v which holds the current
2852 set of registers that are allocated for stack access by aopForSym,
2853 registers allocated in aopForSym for accessing stack symbols are not
2854 any more part of the functions usedRegs field,
2855 * (genCall): some times aopOp is called for a stack variable to be
2856 send, aopForSym might perform the push, if this is true make sure
2857 that genCall doesn't push the variable twice by testing _G.resDirect,
2858 * (genFunction): changed testing for unspecified interrupt number
2859 from 256 to INTNO_UNSPEC,
2860 * modified selection scheme of frame pointer generation. Previously
2861 if function did use local registers a frame pointer was generated,
2862 now a frame pointer is generated only if function has arguments
2863 (that need PLUSW2 register access), or has stack arguments, or the
2864 compiler is not instructed to omit the frame pointer,
2865 * (genEndFunction): before restoring local registers that were saved
2866 in the function preamble, also restore the registers that *might*
2867 have been allocated for stack access,
2868 * (genRet): removed some old comments,
2869 * (genCmp, the active (RN's) version): added a call to the
2870 pic16_genCmp_special function to perform the compare with a more
2871 robust and optimized way,
2872 * (genInline): a feature has been added in inline code generation,
2873 which allows a wildcard variable substitution when writing inline
2874 assembly. Code is incomplete and experimental therefore undocumented,
2875 * (genCast): changed order of aopOp for result and right to allow
2876 aopForSym to directly load the result if possible,
2877 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2878 perform an optimized compare on some selected special occasions,
2879 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2880 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2881 generate an IVT any more,
2882 * src/pic16/main.c (pic16_optionsTable): added command line option
2884 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2885 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2887 * src/pic16/NOTES: Raphael Neider added in list of active developers
2888 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2889 jumptable_end to prevent bug #,
2890 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2891 inCond and outCond fields,
2892 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2893 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2894 turn off register spilling,
2895 * (packRegsForOneUse): synced with other ports' versions although it
2896 is not used currently,
2897 * (pic16_packRegisters): added an optimization while reading
2898 structure bitfields, some registers may be saved (malloc code is
2899 decreased by 80 bytes)
2901 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2903 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2904 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2905 this can be optimized more?
2907 2005-03-10 Raphael Neider <rneider AT web.de>
2909 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2910 genNearPointerGet): (hopefully) fixed access to bitfields via
2911 pointers (p->bitN = x; and x = p->bitN; failed)

3545 Adding support for replacing ljmps with sjmps in jumptables
3546 generated for switch statements. For now you need to set the
3547 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3548 Now 4 algorithms for mcs51 jumptable generation are used:
3549 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3550 addresses loaded pc-relative for up to 112 cases and stack-pushing
3551 target addresses loaded with offset from dptr for up to 256 cases.

3578 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3579 to call when a stack overflow occurs,
3580 * (malloc.h): added CVS Id tag,
3581 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3583 * added libc directory. The current version of LibC contains string
3584 functions, ctype functions and macros and some functions of the
3585 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3586 be extensively tested in the future. Standard disclaimer here.
3587 Library is not automatically build yet. But one can build it by
3588 invoking 'make' inside the libc directory.
3589 * added ADC library under libio. Preliminary version yet.

3598 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3599 * (pic16_storeForReturn): optimized return of 0,
3600 * (genCmp): experimental code for new genCmp which uses PIC18's
3601 special compare&skip instructions. Initial tests fail some times
3602 with variables grater than 1 byte in size, so new code is disabled,
3603 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3605 * (genCast): began a fix to optimize the casting of a bit to another
3606 bit, now assigning a bitfield to another bitfield will fail, sorry,
3607 * src/pic16/main.c: disabled the use of lr-support feature,
3608 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3611 bits with offset (case PO_GPR_BIT),
3612 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3614 * (isBankInstruction): modified to return 0 for no banking instruction,
3615 and 1 for banking instruction,
3616 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3617 caused stop processing pCodes after a inline assembly block,
3618 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3619 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3620 registers when it shouldn't,
3621 * src/pic16/ralloc.c (allocReg): add preliminary support for
3622 supporting a limited set of temporary registers,
3624 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3626 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3627 genDataPointerSet): ensure assignments always copy in MSB to LSB
3629 (loadRegFromAop): recognize CLRH optimization,
3630 (genFunction): optimize RECEIVE iCodes in reentrant functions
3632 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6545 * src/SDCCast.c: added an additional type flow in decorateType() of
6546 opposite direction, see feature request #860006; it's enabled at runtime
6547 by setting the environment variable SDCC_NEWTYPEFLOW
6548 * src/SDCCast.h: changed prototype of decorateType()
6549 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6550 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6551 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6552 see feature request #877103
6553 * src/SDCCval.c: updated call of decorateType()
6554 (valBitwise): fixed bug #882876
6555 (valMinus): added promotion
6556 (valLogicAndOr): result is unsigned
6557 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6558 * src/SDCCsymt.c (computeType),
6559 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6560 must not cause an unsigned operation
6561 * src/pic/glue (pic14emitRegularMap),
6562 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6564 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
6566 * src/pic/pcode.c (PCodeID): commented out left over debug code
6568 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6570 * support/valdiag/tests/overflow.c: added shift tests

6579 * src/pic/pcoderegs.c,
6581 * src/pic/ralloc.h: applied patch from Slade Rich;
6582 added support for multiple code pages and multiple RAM banks on the
6583 PIC 14 port. The ASM files now no longer simply assume all the
6584 code / RAM are in the same page / bank. This means the linker can
6585 safely allocate code/RAM of separate ASM files to different pages/banks.
6586 * doc/sdccman.lyx: added Slade's tips
6587 * src/mcs51/peeph.def: fixed bug #880768

6596 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6599 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6600 strtof is not part of C89 and isn't included with Mac OS X.
6602 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6604 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6626 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
6629 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6631 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6632 loaded with the linker search paths (-L arguments) and the libraries
6633 to be linked with the current source (-l arguments). Changes
6634 currently will affect only the pic16 port.
6635 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6636 include path the port specific paths and port specific libraries,
6637 * gplink command now contains the $3 argument,
6638 * src/pic16/device.h,
6639 * src/pic16/device.c,: structure PIC_device is made public and
6640 renamed to PIC16_device, the same for variable Pics which is renamed
6641 to Pics16. Updated all references to them.
6642 * src/pic16/glue.c (pic16glue): corrected bug with code
6643 initialization which bypassed the variable initializations block.

6653 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6655 Documenting changes from previous commits.
6656 * configure.in (version 1.56),
6657 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6658 when generating output files to configure the pic16 library,
6659 but now I've commented it out, since gputils aren't installed in the
6660 SF compile farm, so library won't compile
6662 * device/lib/Makefile.in (version 1.56): initially I've added in
6663 target 'all' the prerequestive 'model-pic16' so it compiled the
6664 pic16 library, but now I've commented it out for the same reasons
6666 * added targets 'model-pic16' and 'objects-pic16' to compile the
6668 * added target 'port-specific-objects-pic16' to handle the
6669 generated libraries and copy them into the build/ directory
6670 * added target 'clean-intermediate-pic16' to clean intermediate
6671 files into pic16 directory
6672 * in target 'installdirs' added line to create directory pic16 in
6673 the installation path
6675 * device/include/Makefile.in (version 1.11): in target 'install'
6676 added lines to copy all header files to installation path,
6677 * in target 'installdirs' added line create directory for pic16
6678 headers in the installation path

6693 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6694 option so that it actually works. Made it specific to the z80, since
6695 the gbz80 doesn't have these kinds of I/O ports.
6697 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6699 * device/include/z180.h,

6721 Mainly changes to support compilation of the device libraries
6722 * src/pic16/device.c: stack is allocated via symbol and not
6723 via literal number. The symbol is placed in the corresponding
6724 position of the data ram
6725 * (pic16_dump_section): relocatable and absolute uninitialized
6726 data are now emitted in sorted order to reduce section naming,
6727 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6728 weren't marked as being in the access bank,
6730 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6732 Added portion of GNU PIC Library under the directory
6733 device/include/pic16 and device/lib/pic16. These files
6734 contain the declarations of SFRs for the PIC18Fxx2 devices.
6735 The directory is initialized via configure from toplevel.
6737 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6739 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6749 doc/sdccman.lyx: upper case pragmas are deprecated
6751 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6753 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6754 in simpler and even better code

6764 * doc/sdccman.lyx: Moved and added some sections, small changes
6765 all over. Telling LaTeX to be less strict with word spacing
6766 to better keep the right margin. Changed some notes about
6767 maintainance of the ports in section 3.2.1 - is it OK like this?
6769 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6807 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6809 * src/pic16/peeph.def: all peepholes with movff are commented out,
6810 because there is a problem in the pcode peep optimizer,
6811 * src/pic16/ralloc.c: the register allocator can now reuse local

6950 Bug reported from Jesus Calvino-Fraga
6952 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6954 * sdcc.spec: updated
6955 * device/include/Makefile.in: don't install CVS directories

6958 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6959 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6960 * src/ds390/gen.c (genRightShift): fixed bug #870788
6961 * src/SDCCast.c (decorateType): fixed bug #870781
6963 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6965 PIC16 port related changes:
6966 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6967 added variable stackPos,
6969 * gen.c: genCall, assignResultValue: added support for
6970 pushing/retrieving function parameters to/from stack,
6971 genFunction,genEndFunction: setup stack frame for the
6973 genAddrOf: will be changed according to bug 863624
6975 * added files genutils.c and genutils.h which contain gen*
6976 debugged and optimised functions extracted from gen.c
6978 * glue.c: added variable 'externs' which holds extern symbols,
6979 pic16emitRegularMap: is modified to properly handle relocatable
6980 symbols under the new scheme,
6981 pic16createInterruptVect: is modified
6982 pic16printPublics: is modified to emit 'global' assembler directives,
6983 added pic16_printExterns to print extern symbols,
6984 pic16glue: initializes stack/frame pointer in the beginning of
6985 the assembly output. Temporary hack, will be corrected later,
6986 because gplink yet does not support stack and SDCC does not
6987 yet support a type of crt0.o object to create the final binary.
6989 * Removed many lines that contain 8051 legacy code.
6990 * The code is finally placed under a 'code' directive.
6991 * Added port specific options.
6993 * _process_pragma: simplified since now we do not need *special*
6994 include file to define SFR registers. But a separate header
6995 will be needed. This will be developed later.
6996 * _pic16_parseOptions: added, parses port specific options:
6997 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6998 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6999 --preplace-udata-with=
7001 * _pic16_setDefaultOptions: modified to initialize section names,
7002 but hack is temporarly out of order since it needs improvement.
7003 * _pic16_genAssemblerPreamble: configuration words are emitted by
7004 their address instead of their name. This part is incomplete and
7005 supports only the 18Fxx2 devices. Other devices will emit an error
7006 during assembly since they do not contain the same set of config
7008 * _pic16_genIVT: is modified,
7010 * pcode.c: added definitions for some hardware registers that are needed
7012 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7013 All PCI entries are updated. Now LFSR is supported.
7014 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7015 * added pic16_newpCodeOpLit2 to support instructions with
7016 two literal arguments
7017 * pic16_pCode2str: corrected code that emits assembler instructions
7018 with two literal operands and those that have an access bit modifier
7019 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7020 this fixes a bug which caused some labels to be lost, when an
7021 assembler directive was added, i.e. banksel,
7022 * pic16_FixRegisterBanking: improved logic that causes the insertion
7024 * InlineFunction: functions that are called once, are not any more
7025 inlined. This can be a port option in the future,
7027 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7029 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7030 hold the corresponding uninitialized symbols,
7031 * pic16_allocProcessorRegister: registers have explicit marked the
7033 * pic16_allocInternalRegister: registers are explicit marked as
7035 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7036 processing list, so bit registers were lost,
7039 * ralloc.h: added field 'accessBank' and original symbol operand
7040 in register definition,
7041 * removed the field isMapped from register definition,
7043 ** Several functions have been removed from various sources:
7044 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7045 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7046 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7047 pic16_assignRelocatableRegisters
7049 ** others have been introduced:
7050 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7051 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7053 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7055 * support/scripts/inc2h.pl: changed definition of BIT_AT
7056 to emit 'sbit at' instead of 'bit at'. This was a request.
7058 PIC16 port related preliminary changes:
7059 * gen.c: prefixed function popRegFromString with
7060 pic16_ and all references to it corrected
7061 * pcode.c: all pic16_pc_* hardware registers prefixed
7062 with underscore (_),
7063 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7064 * ralloc.c: newReg(): when register is REG_SFR then
7065 set address to rIdx,
7066 pic16_allocProcessorRegister(): marks register wasUsed=0
7067 pic16_writeUsedRegs(): added a call to assign processor
7068 registers via pic16_assignFixedRegisters
7070 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7072 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7073 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7074 variables in unused register banks. Also the SSEG is placed
7075 wherever there is enough space for it, and IDATA can be anywhere
7076 in internal RAM. For now compile using -Wl-Y[stack_size].
7077 The mem file is different for this option as well, since it
7078 makes no sense of talking about DSEG lenght.
7080 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7082 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7328 revision 1.188 (access to fields of a structure at an absolute address);
7329 it breaks with bitfields, extern declarations, and gcse analysis.
7330 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7331 could be assigned through a pointer, so don't complain.

8088 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8089 fetching of the pointer
8090 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8091 copied from genNearPointerSet()
8092 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8093 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8094 If they pop r0/r1 they must be called in the opposite order than aopOp().
8095 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8096 (resp. --stack-auto), prepared for --xstack

8107 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8109 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8110 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8111 type for bits was changed. It resulted in bit variables becoming
8112 global, which is not permitted in PIC 14 assembly output.
8114 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8116 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8118 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8120 Z80 and MCS51 linkers complaint if a public symbol is defined

8129 A few small changes that speed up the peephole optimizer.
8133 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8135 Try to make the peephole optimizer smarter by maintaining
8136 an association between the assembly source code and the
8137 iCodes that originated them. Put this information to use
8138 with a new peephole rule condition "notVolatile" so that
8139 the rules can be aggressive yet still safe.
8144 * src/mcs51/peeph.def
8146 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8150 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8151 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8152 if the left or right operand symbols have the accuse flag set.
8154 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8156 Changed the type of the result of the ! (NOT) operator to char;
8157 previously it returned the same type as the source. This allows
8158 us to eliminate all the genFloatNot functions (all of its target
8159 implementations were very buggy) since !float can use the same
8162 * src/SDCCicode.c (ast2iCode): ! returns char

8164 * src/ds390/gen.c (genNot, genNotFloat),
8165 * src/z80/gen.c (genNot, genNotFloat),
8166 * src/pic/gen.c (genNot, genNotFloat),

8169 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8171 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8172 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8173 during interrupts. Ensure WSAVE is located at a shared bank address.
8174 2. Fixed page selection in some places
8175 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8176 the registers name strings.
8177 4. Fixed "signed / unsigned compare" compiler warnings.
8178 5. The PIC port manages its own allocation of the general purpose
8179 registers, but makes no attempt to reuse them. As a result when
8180 compiling it soon runs out of general purpose registers. Some
8181 additional code was added to the files pcode.c and device.c to walk
8182 through the function call tree and rename the registers so that they
8192 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8193 genPlus() & genMinus() when the result is the same as left or right

8199 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8201 Made bitfield a distinct type from bit so that bitfields
8202 convert as per ANSI C and bits retain their traditional
8203 boolean style behaviour. Implemented bitfield support in
8211 * src/ds390/gen.c: bit v bitfield split
8212 * src/z80/gen.c: New support for bitfields
8213 * support/regression/tests/bitfields.c: reenabled z80,
8216 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8218 Rules 246.x, 247.x relate to bitfields, the others speed up
8219 access to xdata mapped I/O devices.
8221 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8223 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8225 Cleaned up genPackBits and genUnpackBits and added two helper
8226 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8227 for literal assignments in genPackBits (thanks to Frieder for
8233 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8235 Fixed bug #748310 (pointer to function type mishandled when the
8236 function name is omitted). Also fixed a SIGSEGV when a function
8237 attribute (reentrant, etc) is used on a non-function or on a
8238 function but misplaced before the parameter list.
8240 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8242 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8265 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8267 Made the constant following the "interrupt" keyword optional. If
8268 omitted, the function will not automatically be given an entry
8269 in the interrupt vector table (similar to #pragma NOIV, but
8270 less syntacticly kludgy). The interrupt number is also now
8271 range checked. Also fixed a bug in the high order bit example
8278 * support/Util/SDCCerr.c
8279 * support/Util/SDCCerr.h
8282 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8285 * src/SDCCicode.c (operandOperation): rewritten some ops
8286 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8287 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8289 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8290 be re-activated by defining REDUCE_LITERALS)
8291 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8292 unsigned, but are signed by default
8293 * src/SDCCval.c (constVal): rearranged
8294 * src/SDCCval.c (valMod): preliminary fix
8295 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8338 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8339 * src/SDCCval.c (valDiv, valMod): fixed signdness
8340 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8341 signedness of modulo, left and right shift

8747 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8748 the regression tests I'm not brave enough to enable 245.b, 245.c

8750 Using pdflatex this will give you a hyperlinked pdf file with
8751 bookmarks. (prepend '%' before /usepackage if this breaks something)

8800 * src/SDCCmain.c: linkOptions is changed to set *,
8801 added if/endif conditional macros to remove options help
8802 messages from optionsTable when a port is not configured, added
8803 support for the PIc16 port in the ports table, when executing
8804 the compiler with no port specified on command line, a default
8805 port is selected with the new macro DEFAULT_PORT which is
8806 defined in port.h, in setDefaultOptions() linkOptions is removed
8807 from initialization assignment, since now it is a set,
8808 parseCmdLine uses setParseWithComma for linkOptions, in
8809 linkEdit() linkOptions are accessed with new function indexSet()
8810 which returns the i'th item of a set variable. See SDCCset.c, in
8811 linkEdit() when calling buildCmdLine(), added linkOptions as
8812 last argument. Now users can pass arguments to gplink via the
8813 -Wl option, main() uses pic16glue() to glue up pic16 programs

8825 * src/pic16/glue.c: commented out some error producing lines
8826 * src/pic16/main.c: __config directives are commented out to stop
8827 gpasm complaining and test the linkage with gplink, _linkCmd and
8828 _asmCmd changed to be more gplink and gpasm friendly
8829 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8830 produced an error when parsed, peep rule 12 is added to utilize
8831 movff, but it is commented out since the pCode does not support
8832 yet a command with 2 address arguments
8834 2003-05-18 <johan AT balder>
8836 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8863 2003-05-11 Borut Razem <borut.razem AT siol.net>
8865 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8866 the path of bin directory, so that PATH is the only env. variable, which has to be set
8867 in case of standard installation.

9950 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9951 not bytes. Function summary() which creates a memory usage summary
9952 file with extension .mem. Reports of overlaping stack and small stack
9953 size. If the space for the stack is less than 16 bytes aslink trows a
9956 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9957 the 8051. Option 'y' for memory summary output file.
9959 Changes to sdcc (All the changes are marked with 'JCF'):
9961 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9963 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9964 overlaying area for it (uses RegBankUsed[4]).
9966 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9967 bank zero as used by default. By default aslink locates the stack
9968 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9969 the creation of the .mem file. Delegates the allocation of data area
9970 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9971 the begining of the stack area to aslink.
9973 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9974 glue() in SDCCglue.c creates an area for it.
9976 2002-09-03 Borut Razem <borut.razem AT siol.net>
9977 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9978 sdcc/src/pic/glue.c:
9979 introduced atexit() handler for teporay files removal in case of
9980 errors, assertions, ...
9982 2002-08-29 Borut Razem <borut.razem AT siol.net>
9983 * sdcc/support/cpp2/auto-host_vc_in.h:
9984 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9985 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9986 Maybe there is a similar problem with BORLANDC? It should be checked!
9988 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9989 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9990 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9991 was not executed, and the compiler (cl) launched a warning:
9992 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9994 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9995 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9997 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9998 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10000 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10001 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10002 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10003 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10004 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10005 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10006 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10007 - added Release configuration in VS projects
10008 - review of compiler an linker options
10009 - VC .exe files are generated in bin_vc directory, not to interfere
10010 with binaries generated from other projects (cygwin, mingw, bcc ...)
10012 * sdcc/src/yacc.dsp: added
10014 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10015 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10016 and insert the version number definitions from .version
10018 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10020 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10021 added - genarate auto-host.h using auto-host_vc_in.h as template
10024 removed from CVS, generated automatically
10026 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10027 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10029 2002-08-11 Borut Razem <borut.razem AT siol.net>
10030 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10032 2002-08-10 Borut Razem <borut.razem AT siol.net>
10033 * src/SDCCmain.c (main):
10034 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10035 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10036 The consequence was that some temporary files were not removed.
10039 unification of code in functions tempfilename() and tempfile():
10040 function tempnam() is defined in Visual Studio 6.0 and .NET
10042 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10044 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10045 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10046 - removed compiler command line option /WX: Treats all warnings as errors
10047 - update a list of source files, included into the project
10049 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10050 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10051 changed project type to Generic Project so that can be correcly converted to VS.NET project
10053 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10055 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10057 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10059 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10060 added return 0 statements after assert() to make compiler happy
10062 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10063 added newline in the def file to keep MSC compiler satisfied
10065 * sdcc/src/z80/gen.c:
10066 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10067 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10068 - solved MSC error in function aopDump()
10070 * sdcc_vc.h: define PREFIX as "\\sdcc"
10072 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10073 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10121 Added -p option. Allows port dependent processor to be specified.
10124 Initialized the new field char *Processor field to NULL in all ports
10127 Compiler generated registers for interrupt context saving
10128 were not getting allocated.
10130 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10133 Fixed left shift. Will promote the left side of a left shift
10134 if a) left shifting more than size of operand or b) when assigned
10135 to something size > size of left side
10137 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10245 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10247 * sdcc/src/SDCCloop.c:
10248 Previous fix was not good. basic blocks that have "break" or "return" are
10249 not really partof a loop , but live ranges used in these blocks should
10250 be live thru the entire loop, so set partOfLoop but don't add them to
10253 2002-02-21 <johan AT FRIJA>
10255 * src/SDCCcse.c: fixed bug #514308
10257 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
